METHOD FOR SIMULTANEOUSLY ABATING NITRIC OXIDES AND NITROUS OXIDES IN GASES CONTAINING THEM

摘要

we can treat industrial gases prior to their release to the atmosphere of theirnitrous oxide n2o and no x by reaction with ammoniain the circulating at temperatures of 200 to 600 deg. c in acatalyst based on zeolite beta. the method is appliedin particular to the treatment of tail gas from the production workshop of acidnitride.
